In this article, different thiacloprid formulations, by the directions of different kinds of dispersing agent and wetting agent, disintegrant agent, were made up and check out according to indexes of suspensibility, disintegration etc. The direction of formulation was chosen, which was made up of thiacloprid 36%, CBZ 10%, naphthalene sulfonate 10%, ammonium sulphate 20%, and calcium carbonate(light) 33.2%. The test of thermal storage stability showed that the decomposing rate of thiacloprid was less than 1.1%, suspension rate more than 93.3%, wetting time less than 23 s, disintegration time less than 33 s, which was in accord with the sandard of quality criterion of WG.
